The loop bandwidth f
C
should be chosen to fulfill the Gardner’s stability criteria by at least a factor of 10,
typical values are 50.
ζ
= 0.9 ensures a good transient response.
And finally the frequency relationship is defined as
With the above values the resistance can be calculated. The example is shown for a loop bandwidth

A.5.3.2 Jitter Information
The basic functionality of the PLL is shown in
Figure A-2
. With each transition of the clock f
cmp
, the
deviation from the reference clock f
ref
is measured and input voltage to the VCO is adjusted
accordingly.The adjustment is done continuously with no abrupt changes in the clock output frequency.

jitter. This jitter affects the real minimum and maximum clock periods as illustrated in
Figure A-3
